Chen Dawei said to Li Jiayi: "We will investigate the incident of attacking the police, and tell me about your eldest brother Li Jiaren." ”

Li Jiayi said: "My eldest brother? He's fine, I've said everything I have to say. ”

Chen Dawei said with a straight face: "Li Jiayi, how long do you have to hide it?" Now that you say that there is still a chance to get leniency, you have to think clearly, you don't say what others will say. ”

Li Jiayi will sit in the interrogation room, and his heart is like a hundred claws scratching his heart. He closed his eyes.

Chen Dawei said to Li Jiayi: "It seems that you still haven't thought it through yet, let me tell you, the person you are waiting for will not come." ”

Li Jiayi lowered his head and said, "Brigade Chen, can I smoke another cigarette?" ”

Chen Dawei handed over a cigarette, and Li Jiayi said: "That night twenty-three years ago, it was not my sister-in-law who came to me, but my eldest brother Li Jiaren. ”

Chen Dawei said: "Didn't you say last time that it was your sister-in-law who came to you?" Why are you lying? ”

"Because... Because I and my eldest brother helped Siping escape. Siping killed someone, I discussed with my eldest brother and asked me to call my sister-in-law to go to the township police station to report the case. My sister-in-law is injured, and the police will not suspect that the time is deliberately delayed on the road, so that Siping can run farther. ”

Chen Dawei said: "You have a good plan, you can take a look at our interrogation transcript, and if there is no problem, you can sign it!" ”

Chen Dawei came to the monitoring room and asked people to play the interrogation video over and over again, and he was sure that Li Jiaren was not lying.

Ma Jianchao, who came back, said: "Boss, Li Siping's side has been arranged, what should I do now?" There is still no new breakthrough in the case.

I'll wait for you to have nothing to do in the past few days, so I'll take a closer look at the evidence left by Fang Yuan. I made a software that mimics the scene of the hoe murder case, you can come and take a look. ”

Chen Dawei said: "Okay, Chaozi, you can, let's take it to the conference room and watch it together." ”

Li Sizhong has been like an ant on a hot pot these days, begging people everywhere to save his father, but one sentence everyone gave him was, "Your family has provoked people who shouldn't be provoked this time, and it's useless to find anyone, the minister has personally sent a message to strictly investigate." ”

In the conference room, Ma Jianchao took out the evidence sorted out by Fang Yuan, in fact, twenty-three years have passed, and the so-called evidence is a few pictures and data records from the crime scene at that time, and the crime tool hoe has long been lost.

"Ma Jianchao, what are you doing?" Someone in the conference room said impatiently.

Ma Jianchao said: "Everyone, please look at the big screen, this is my simulation software for restoring the scene of the murder in equal proportions according to the data of the hoe case."

At that time, the data at the scene recorded that the head of the deceased Tian Xiuhua was directly cut off from the neck with a hoe, and the deceased was sleeping at the time, and the angle of the neck break was tilted towards the head, and the vertical angle with the neck was 10 degrees. ”

"What does that mean?" Someone asked.

Ma Jianchao continued: "The height of the earthen kang in the deceased's room was one meter two, and the murderer's tool was a hoe. The length of the hoe handle is 1.5 meters, and the murderer must be within 1.5 meters from the kang if he wants to kill.

Everyone looks at this murder scene software, and the murderer wants to cause such a neck fracture angle, height is the key. As long as you enter the height of the murderer, you can get an angle of the broken neck, Phineas, tell me what your height is? ”

"One Meter Five Six"

There was a burst of laughter in the conference room, but when Ma Jianchao typed 1.56m on the computer, the conference room was silent.

According to the software designed by Ma Jianchao, the angle obtained is -8 degrees. Chen Dawei reported his height of "one meter eighty-three", and when Ma Jianchao entered, the conference room burst into applause.

Chen Dawei looked at the thirteen degrees displayed on the screen, and he gave Ma Jianchao a thumbs up.

Chen Dawei asked Ma Jianchao: "Chaoson, what is the accuracy of your software?" ”

"± 0.01 degrees"

Chen Dawei said excitedly: "Chaozi, good job!" This case is solved, and you take the first credit. Everyone immediately went down to measure the height of Li Jiayi, Li Jiaren, Li Siping, and Yan Chunhua, and they must be accurate. ”

Half an hour later, the height data of the four people was placed on the table. Ma Jianchao typed one by one:

Li Jiayi is 1.72m 4 degrees tall

Li Jiaren is 1.80m 10.01 degrees tall

Li Siping is 1.65m -5 degrees tall

Yan Chunhua is 1.62m -7 degrees tall

Seeing the data displayed on the screen, Chen Dawei was speechless for a long time, he had to admire Fang Yuan, Fang Yuan had already said that the murderer was someone else. The data has said it all, the murderer who really killed Tian Xiuhua was Li Jiaren, and his father-in-law killed his daughter-in-law, but blamed his neurotic son, but why did all this happen?

Chen Dawei walked out of the conference room, his mood was very complicated. He unconsciously took out his mobile phone and made a call to Fang Yuan, "Fang Yuan, the case has progressed, and there is another real murderer in the hoe case, it is Li Jiaren." ”

"What? It was Li Jiaren who killed Tian Xiuhua, who was the father-in-law of the deceased, but why is this? Fang Yuan on the other end of the phone was just as surprised as Chen Dawei.

"Why? It may be that only the parties themselves know. Chen Dawei replied weakly.

Fang Yuan said: "Boss, you should be happy that there is progress in the case, why does it sound like a low mood." Is it because your dad handled the case at the time? You don't have to blame yourself, the conditions for handling the case at that time were insufficient......"

Chen Dawei interrupted Fang Yuan's words and said, "I'm fine, you don't have to comfort me, how is your injury now?" ”

Fang Yuan smiled and said, "What? Care so much about me, didn't you just watch it in the afternoon? ”

Chen Dawei said: "I'll hang up if it's okay, I'll go to try the case." ”

Chen Dawei has been avoiding his feelings, saying that he doesn't care, and he is more anxious than anyone else.

Chen Dawei walked into the monitoring room, and the interrogation of these four people continued, and the interrogation lasted for more than half a day, especially at three or four o'clock. Li Siping had already fallen asleep in a chair in the interrogation room, and the other three criminal police officers were still interrogating.

The criminal police asked a question over and over again, that is, the murder happened 23 years ago.

This was deliberately arranged by Chen Dawei, he just asked them to recall the incident over and over again, and they could always find loopholes if they told too many lies.

Li Jiaren in the second interrogation room had obviously begun to be irritable, and he kept biting his lower lip, he wanted to remind himself.

In the third interrogation room, Yan Chunhua cried and told what happened over and over again, and she shook her head and said that she never wanted to recall it again. She was on the verge of collapse, and the time had come, Chen Dawei decided to start interrogating Yan Chunhua.

Chen Dawei pushed the door open, and as soon as Yan Chunhua saw Chen Dawei, her neck shrank back. This was a normal reaction, because she had seen Chen Dawei who was furious, and recalled the scene when Chen Dawei's cold gun was pointed at Li Jiayi's head, as if the muzzle of the gun was now in her head.

Chen Dawei sat on the chair opposite Yan Chunhua and said, "You're afraid of me? ”

Yan Chunhua nodded and said, "Don't ask me, I don't know anything, I have already told you everything I know." ”

Chen Dawei said slowly: "Really? I don't think so, so I'll ask you whether Tian Xiuhua was killed by Li Jiaren alone, or are you also an accomplice? ”
